Conducted Immunity


The PSG-300 contains a linear precision power amplifier with a wide bandwidth (DC-300 kHz), suitable for all applications concerning fast alternating signals at high output power. The built in generator provides sine, square and triangle waves. Communication between PSG-300 and PC is via USB connection. The application software is suited for general power generator applications and for immunity tests according to IEC/EN 61000-4-16 as well as to IEC/EN 61543. Short term tests are enabled by phase controlled switching of an external power source (optional). The PSG-300 is equipped with a silent, temperature-controlled fan. Internal safeguards protect the amplifier from overheating and high power dissipation. They also assure protection against short-circuits and overload.

The number one choice for all applications with the need for fast and powerful signals, e. g.:

Simulation of DC / AC supply lines

Control of piezo actors

Generation of magnetic fields with Helmholtz or similar coils

Immunity testing according to IEC/EN 61000-4-16, IEC/EN 61000-4-19 AND IEC/EN 61543

Calibration devices etc.
